Biotin is renowned for supporting healthy hair, skin, and nails. This B-vitamin helps synthesise keratin, the protein that makes up hair structure. While most people get enough biotin from their diet, supplements can help if you’re deficient, reducing thinning and breakage while improving shine and density. Natural sources include eggs, nuts, whole grains, and leafy vegetables. Still, biotin supplements are popular for addressing brittle or thinning hair.
